23 Claims.

This invention relates generally to automatic machines for feeding safety pins from aconglomerate mass to a point of use, the pins being fed in the same position relative to each other and 5 in definite positive steps.

An object of this invention is the provision of a feeding mechanism whereby safety pins may be fed automatically from a conglomerate mass to a magazine one at a time and in the same relative 10 position.

Another object of the invention is the provision of a feeding mechanism whereby safety pins may be discharged into collaterally arranged chutes or slots in the same relative position, and

15 releasing pins one at a time and in a definite order from said chutes toa single chute from which the pins may be released one at a time as needed to meet particular requirements.

Other objects of the invention will, in part, be

1 apparent and will, in part, be obvious from the following description taken'in. conjunction with the accompanying drawings, in which:

and 4 to 7, inclusive; and

Fig. 12 is a View in section as taken on line XII-XII of Fig. 10.

Throughout the drawings and the specificaii i) tion, like reference characters indicate like parts. The machine illustrated in the accompanying drawings, as embodying the principle of the invention in what now appears to be, a preferred form thereof, is designed to feed safety pins at 55 a high rate of speed for use in connection with taken on line VII-VII the manufacture of marking tags. As shown in Fig. 3, the tags with which such pins are used comprise a safety pin S. P. and a tab T. of cloth. or other material, one end of which is wrapped 'or folded about the back bar B. B. of the pin and fastened by means of a staple S. T., preferably a wire staple. I The feeding device embodying the invention is designed to receive a quantity of pins, without regard to orderliness of arrangement and to feedv the pins to a magazine one at a time and in; exactly the same relative position. In the form illustrated, the pins are fed head forward with the back bars thereof all on the same side of the magazine. 7

From the magazine, the pins are fedone at a. time in timed sequence to a suitable landing where the tags are formed. v Since a feeder of this character is designed, in the interest of economy and low production-cost, to operate at high speed, it follows that each pin must be delivered from the magazine to the land--. ing without any loss of time. This is accomplished by giving the pin a high acceleration the. moment it is released from the magazine. To accomplish this function the pin, when released from the magazine, is propelled by an'air blastto the landing to be in position tobe operated .on by a suitable tag forming mechanism such as shown in my copending divisional application Serial No. 141,380, filed May 7, 193 7,

In Fig. 1 of the drawings, I have illustrated my pin feeding device as comprising a pin-feeding mechanism I, a magazine 2, to which the pins are fed by mechanism I, one at .a time, head for:

Ward with the back bars thereof on the same side and stored head on tail, in connection with a tag forming machine 3 driven by a motor M.

The feeding mechanism I, magazine 2 and ma-. chine 3 are carried on a table or support 5 of such height as will provide the most convenient operating conditions for the operator. The lower end of the magazine 2 terminates in a curved portion 6 into which a continuous air blast is directed by means of a pipe 1 that is connected to a source of supply of air under pressure (not shown). Stops 8 and 8' (see Fig. 2) secured to a pivoted lever 9 operate in the lower end of the magazine at a point above the curved portion-'6' to release pins one at a time into the curved por tion 6, and by suitable mechanism delivered in timed relation with the tag forming'operationslof machine 3. I As ma'y be seen in Fig. 2, lever 9 mounted on a pin 9, is disposed in is pivotally an opening- .stop 8 projects is Q located in one side of magazine 2, and carries stops 8' and 8 at its upper and lower ends, respectively. The face of the lever from which inclined outwardly so that when the lever is in its full line position, stop 8' extends into the magazine in position to support a pin thereon, the stop extending through the loop defined by the back bar and bar pin and under the tail of such pin. Therefore, when stop 8 is in this position, the column of pins above the same is also sup-ported thereby. When lever B is turned to the broken line position, stop 8 releases the pin which it supports and. this pin comes to rest on stop 9 which now extends into the magazine. When lever 9 is returned to its full line position, the pin which has dropped down on stop 8 is released to section 6 of the magazine and propelled by the air blast to the landing place In. Thus as lever 9 is oscillated to its full and broken line positions, pins are dropped one at a time into portion B-of the magazine.

Lever 9 is operated by a reach bar B one end of which is secured to the lever by pin C that passes through an elongated slot D formed in the bar. A tension spring E connected to pin C and a pin F secured to the bar B maintains the pin C in yieldable contact with the right hand end of slot D, as seen in Fig. 2, but in case stop 8 should contact the head of a pin, the spring will yield as bar B moves and thereby avoid breaking any of the parts above mentioned. Reach bar B is connected to a system of suitable levers which effect the above described operation of lever 9. Reach bar B is connected to and oscillated by lever |80 of the tag-forming mechanism as shown in my aforesaid copending application Serial No. 141,380, filed May 7, 1937.

When a pin drops into portion 6, the air blast from pipe 1 accelerates the same and almost instantly delivers it to landing H] of the machine, wherein the head and tail of the pin are suitably supported. When in this position, one end of suitable tab stock (not shown) may be folded around the back bar of the pin S. P. and a staple may be pushed through the overlapping portions of tape and clinched to form a tag, as shown in Fig. 3. A machine suitable for making tags is disclosed and described in detail in my copending application Serial No. 141,380, filed May '7, 1937, which is a division of this application.

Pin feeding mechanism The pin feeding mechanism comprises a rotating drum 39 mounted on an overhanging sta tionary shaft 3|, which is supported at one end by an upright 32 carried by the table of the machine, a guiding device 33 into which pins are discharged from drum 39, and means 35 for eifecting the delivery of pins one at a time to the magazine 2.

The drum 39 comprises a series of blocks 34 which effect the delivery of pins in a definite position tothe guiding device and these blocks are secured at their opposite ends to rings 38 and 31. Ring 36 is formed preferably as an integral part of a plate 38 which constitutes a closure for one end of the drum. Plate 38 is provided at its center with a relatively long hollow hub 39 through which the shaft 3| extends and constitutes the journal for the drum.

The other end of the drum 30 is closed by a plate 4| having a hub 42 through which shaft 3| extends, plate 4| having sliding contact with ring 31. A pin 43 passing through the hub and shaft holds plate 4| stationary relative to the drum. A hopper-like funnel 44 is formed at the upper portion of plate 4| and this funnel terminates in an opening 45 through which pins may be fed to the interior of the drum. The lower portion of plate 4| may be provided with a window 46 in order that the operator may, by observation, determine when to feed pins to the drum so that a sufficient quantity may be main tained therein.

Drum 39 may be driven from a countershaft 41 having a pinion 48 thereon that meshes with a gear 49 loosely mounted on shaft 3| but secured to plate 38. A grooved pulley 59 interposed between gear 49 and plate 39, drives means 35 through a belt 5|. A motor 52 drives the countershaft 41 through a pinion and gear connection 53, 54.

An understanding of the details of construction of drum blocks 34 may be had from the following description taken in conjunction with Figs. 4 to 12, inclusive.

Each block 34 is provided on its inner face with a plurality of parallel rectangular recesses or slots 59 which lie in parallel vertical planes disposed at right angles to the axis of rotation of the drum. The base of each slot slopes outwardly from a point adjacent the forward or leading edge 51 of the slot towards the outer face thereof and terminates at the trailing edge 58 in an opening 59 through which the pins discharge.

As was stated previously herein, the pins are delivered to landing I9 one at a time in exactly the same relative position. For the purpose of making tags it is preferred that the pins be 5.

fed head forward with the back bar B. B. towards the machine and the bar pin facing mechanism M. This requires, for the arrangement shown, and the direction of pin feed, that the pins shall be delivered to the magazine with the thinnest portion of the head, that is, the portion to which the back bar is attached, facing the drum (see Fig. 5). To insure that each pin shall always be delivered in this manner to magazine 2, openings to the shape of the heads of the pins with the widest part of each opening adjacent the bottom of slots or recesses 56 and with the narrowest part thereof extending towards the inner face of the drum (see Figs. 5, 8, 11 and 12). Thus, if a pin falls into any of these slots or recesses with the head towards opening 59, the pin can only pass through this opening if it is in the proper position, that is if the bar pin lies against the bottom of such slot.

In order to prevent the pins from discharging through openings 59 tail first, a lug 5| is formed on each of the walls of each slot. The space between these lugs is wider than the tail of a pin but narrower than the head thereof so that if the tail is forward, the head cannot pass between the lugs and the pin is therefore prevented from being discharged from the drum to the guiding device 33 and into magazine 2. However, when the head is forward and in that portion of a slot 56 located between an opening 59 and lugs El and with the bar pin against the bottom of slot 55, the pin will pass through opening 59.

To aid or increase the facility with which pins tumble into these slots or recesses, the inner edges of the recess walls are extended inwardly from the inner face of each block 34 and are tapered as at B2.

The outer faces of blocks 34 are provided with grooves 64 that start at the leading edges there- 2 head forward and 59 are shaped to conform 2,os3,5s4 3 of and terminate at the outer surface of the drum. 5, the coil spring 94 of a finger moves between the These grooves are disposed in alignment with the tail and head of abutting pins while projection discharge openings 59 and act as guides or chutes 9| moves away from the pin which it supports, for directing the pins into the guiding device 33. allowing the same to drop into the magazine. These slots also act as elevators to carry pins Each finger is also provided with a cam surface 95 which have passed through openings 59, before adapted to cooperate with cam. 86. Cam 86 is reaching the point of delivery to guiding device provided with a plurality of projecting elements into the guiding device. This elevator action is intervals, the spacing being the same as the 10 accomplished by placing a curved plate 66 on the spacing of fingers 85. Thus as the cam-rotates,

However, when a finger 85 is turned by order to make certain that pins shall not be cam 86 in a clockwise direction, as seen from Fig. lodged in the grooves of the drum block, a rotatpredetermined position ing brush I03 is provided. This brush is as long as blocks 34 and is mounted immediately above the drum for rotation on a shaft (not shown) that is journalled in a bearing H35. The brush is driven by motor 52 through a connection comprising grooved pulleys Hit and IT! and a belt I08, and such direction that the portion of the brush contacting the drum moves in the same direction as drum 3 Thus any pins that remain in slots at are brushed out of the same and into the interior of drum 3%. To effectively accomplish this function, the brush is driven at a higher peripheral speed than that at which the drum is driven.
